Construction firms are knowledge-intensive organisations as employees use knowledge in their day to day activities; however, managing this knowledge is essential for improved service delivery. Knowledge Management (KM) has been affirmed to be of great benefit and improve the performance of organisations and particularly quantity surveying firms in Nigeria so, therefore, the need to assess the factors critical to the implementation of KM. Quantitative data was collected through the use of questionnaire from eighty-six quantity surveyors from quantity surveying firms in the southwestern geopolitical zone of Nigeria which comprises of six states using census sampling. Descriptive and inferential statistics were used to analyse the data collected, and the result discussed. Mean Item Score was used to rank the factors while data reduction technique was used to ascertain the factors critical to the implementation of KM. The Kaiser-Meyer-Olkin measure of sampling adequacy and Bartlett’s test of sphericity were conducted before the data were subjected to principal component analysis and the results indicated that the data set is suitable for factor analysis. Five constructs of CSF, namely; Organisation and Leadership, Resources, Management involvement, Information technology and culture were developed from the Principal Component Analysis (PCA) with a significant value ranging from 0.524 - 0.776. The reliability of each construct was tested using Cronbach Alpha coefficient, and the values arrived at are; 0.87, 0.885, 0.882, 0.903 and 0.749 respectively. The study revealed that the significance of KM critical success factors is well acknowledged by quantity surveyors in quantity surveying firms and the findings contributed to knowledge by introducing five factors critical to the success of KM. The study recommends that these factors should be given adequate attention for successful KM implementation in quantity surveying firms in Nigeria.

Background: The Intermittent Claudication Questionnaire (ICQ) is a short questionnaire for the assessment of health-related quality of life (HRQOL) in patients with intermittent claudication (IC). The objective of this study was to translate the ICQ into German and to investigate the psychometric properties of the German ICQ version in patients with IC. Patients and methods: The original English version was translated using a forward-backward method. The resulting German version was reviewed by the author of the original version and an experienced clinician. Finally, it was tested for clarity with 5 German patients with IC. A sample of 81 patients were administered the German ICQ. The sample consisted of 58.0 % male patients with a median age of 71 years and a median IC duration of 36 months. Test of feasibility included completeness of questionnaires, completion time, and ratings of clarity, length and relevance. Reliability was assessed through a retest in 13 patients at 14 days, and analysis of Cronbach’s alpha for internal consistency. Construct validity was investigated using principal component analysis. Concurrent validity was assessed by correlating the ICQ scores with the Short Form 36 Health Survey (SF-36) as well as clinical measures. Results: The ICQ was completely filled in by 73 subjects (90.1 %) with an average completion time of 6.3 minutes. Cronbach’s alpha coefficient reached 0.75. Intra-class correlation for test-retest reliability was r = 0.88. Principal component analysis resulted in a 3 factor solution. The first factor explained 51.5 of the total variation and all items had loadings of at least 0.65 on it. The ICQ was significantly associated with the SF-36 and treadmill-walking distances whereas no association was found for resting ABPI. Conclusions: The German version of the ICQ demonstrated good feasibility, satisfactory reliability and good validity. Responsiveness should be investigated in further validation studies.

Aim: to determine the association between clinical laboratory parameters, the production of cytokines (IL-17A, -23, -33, -35), and specific IgM and IgG in the serum of patients with Lyme borreliosis without erythema migrans. Patients and Methods: complete blood count, the concentrations of IL-17A, -23, -33, -35, and the levels of specific IgM and IgG were measured during acute infection and convalescence (n=30). The control group included age- and sex-matched healthy individuals (n=30). Statistical analysis was performed using the StatSoft Statistica v 10.0 software (parametric and non-parametric methods and multifactorial analysis, i.e., principal component analysis). Results: most (80%) patients with Lyme borreliosis without erythema migrans are the people of working age. In most patients, the combination of the specific antibodies against Borrelia afzelii and Borrelia garinii (76.7%) and severe intoxication and inflammatory process (100%) were detected. Moderate and severe disease associated with meningism was diagnosed in 90% and 10%, respectively. The mean duration of hectic period was 8.3±1.27 days. Abnormal ECG was reported in 40% of patients, i.e., conduction abnormalities in 20%, sinus bradycardia in 16.7%,and sinus tachycardia in 3.3%. The clinical laboratory signs of hepatitis without jaundice were identified in 26.7%. During treatment, the significant reduction in band and segmented neutrophil counts as well as the significant increase in platelet count were revealed compared to these parameters at admission. Abnormal cytokine levels (i.e., the increase in IL-17A, -23, -33 and the deficiency of IL-35) were detected. Conclusions: multifactorial analysis has demonstrated that the severity of immunological abnormalities in patients with Lyme borreliosis without erythema migrans is associated with fever, cardiac and liver disorders, the high levels of IL-23 and IL-33, and the lack of IL-35 and specific IgM and IgG.
